Do you keep Kosher, following God's laws on food and drink? If not, why not?
"Because as Christians, we live under Grace, not the Law." For two millennia, that's been the accepted doctrine of the Christian churches - all of them, not just the Catholics, Orthodox, or Protestant.
So if we need not keep Kosher, etc., why do you insist we follow certain other Laws?
Seems to me you've got an axe to grind, here.
